What aspect ratios are available?

Preset ratios include 1:1, 16:9, 4:3, 3:2, and more. You can also use freeform cropping for any custom dimensions.

Does cropping reduce image quality?

No. The cropped output retains the original resolution and quality of the selected area.

Can I crop to exact pixel dimensions?

Yes. After selecting the crop area, you can see the exact pixel dimensions and adjust accordingly.

Are my images uploaded to a server?

No. All processing happens in your browser. Your images stay on your device.

What this tool does

Crop any image to a specific aspect ratio or freeform rectangle. Drag the crop box visually, or set exact pixel dimensions. Output the cropped result as JPG, PNG, or WebP. Runs in your browser — no upload.

When to crop instead of resize

Resizing scales the entire image down or up while preserving what is in the frame. Cropping changes what is in the frame, throwing away pixels outside the crop box.

Use crop when:

The image has dead space (sky, blank background, a distracting element near the edge) that you want gone.
You need a specific aspect ratio that the source does not have — converting a 16:9 landscape to a 1:1 square, or a portrait phone shot to a 4:5 social-feed shape.
You are zooming in on a subject — the cropped output looks closer to the subject than the original.

Use resize when the framing is correct but the dimensions are wrong. The two operations stack: crop first to get the framing, then resize to get the final pixel dimensions.

Common aspect ratios, by destination

1:1 (square) — Instagram feed, Twitter profile, most avatars. Symmetrical and platform-agnostic.
4:5 (portrait)— Instagram's tallest allowed feed shape. Takes more vertical real estate in the feed than a square.
9:16 (vertical) — TikTok, Reels, Stories, vertical video thumbnails. Phone-shaped.
16:9 (landscape) — YouTube thumbnails, presentation slides, most video.
1.91:1 (OG card) — Open Graph link previews on Facebook, LinkedIn, Twitter, Slack. Closer to 16:9 than to a clean ratio.
3:2 (DSLR native) — what most digital cameras shoot natively. Print sizes 4×6, 6×9, etc. line up here.
2:3 (portrait print)— Pinterest's recommended pin shape and standard portrait photo prints.

The rule-of-thirds and why crop matters

A crop is a composition decision more than a technical one. The rule of thirds — placing the subject at one of the four intersection points of a 3×3 grid — is the default composition that almost always reads well.

Most native phone cameras display the rule-of-thirds grid when you tap and hold to expose. If your source image was not framed thoughtfully, cropping is your second chance to place the subject deliberately.

Resolution after crop

Cropping reduces the pixel count of the output by whatever percentage of the image you discarded. If you crop a 4000×3000 image down to a 1500×1500 square, the output is only 1500×1500 — not 4000×4000. Plan for this when the downstream display size matters.

Browser-only execution

The crop is a canvas operation: copy a rectangular region of the source image into a new canvas, then export the canvas as your chosen format. Everything happens in your tab. Your image, which might include a person's face or sensitive context outside the crop window, never gets uploaded.
